I'm always skeptical of using drugstore hair dye kits, because I simply don't know what the outcome will be. I've colored my hair at home and have had it end up as a patchy mess, and even after that, I decided to give this product a try. As for the smell, it was not nearly as bad as other hair dyes I've used, and it was actually quite tolerable. After conditioning and rinsing my hair, I was very impressed with the outcome. My hair was shiny and evenly colored, and it looked healthier than before despite the fact that I had previously put a bunch of chemicals in it. The reason I gave 3 stars is because the color only lasted for a couple weeks before fading, but that's something that can be forgiven for an affordable, decent quality hair color product.
